This tutorial will guide you through a demo token system. We will use Dapple to build, test and deploy our contracts.

Installing Dapple and the Solidity compiler

First of all, make sure you have Node.js version 5.0 or later:

$ node --version
v6.0.0

Now install Dapple using npm:

$ npm install -g dapple

In order to deploy your contracts to the Ethereum testnet or mainnet, you will need a running Ethereum RPC endpoint, such as provided by geth (instructions).

Although this is sufficient to start developing smart contracts, we highly recommend that you install the native Solidity compiler as well (instructions). While not strictly necessary, the Solidity compiler written in JavaScript which is bundled with Dapple is very slow and may have other problems.

If you want to use some of the more advanced features of Dapple, you will also need to install IPFS (instructions).

Configuring Dapple

After you've installed everything, it's time to configure Dapple. Running dapple config will guide you through the setup process and create a ~/.dapplerc file in your home directory. This file contains information about how to connect to the Ethereum RPC and IPFS endpoints.

Starting your Ethereum node

When experimenting with deploying contracts, you will want to use the non-production network meant for testing (known as "Morden"), which is done by giving the --testnet option to geth:

$ geth --testnet account new
$ geth --testnet --rpc --unlock 0

The second command starts an Ethereum node for Morden with an RPC server listening on localhost:8545 (the default port), and the first account unlocked so that you are able to sign and publish transactions from it.

Finally, you will need some ether in order to pay the gas cost of deploying contracts or publishing other transactions from your account. You can get free ether for Morden here: http://faucet.ma.cx:3000/
